ROLL FOR COTTON-GINS AND MACHINES FOR BURRING WOOL.

Specification of Letters Patent.

Patented Oct. 1, 1912.

Application filed January 18, 1912. Serial No. 671,824.

To all whom it may concern:

Be it known that I, GRABEL E. U. HUOK- ABY, a citizen of the UnitedStates, and resident of Houston, in the county of Harris and State ofTexas, have invented certain new and useful Improvements in Rolls forCotton-Grins and Machines for Burr-ing Wool, of which the following is aspecification.

This invention has relation to rolls such as are utilized in machinesfor ginning cotton or removing the burs from wool. In such machines,there is employed a stationary blade on one side of which is located aroll in close proximity to the edge thereof to engage thefibers whichproject beyond the edge and draw them between it and the blade. On theother side of the stationary blade is mounted a reciprocating oroscillating blade which engages the fibers and removes therefrom thecotton seeds or the burs as the fibers are being drawn past thestationary blade by the roll. It is necessary Lee that the roll shouldbe so constructed as to present a roughened surface or with minute.projections so that the fibers may be engaged and drawn positively pastthe stationary blade. T o accomplish this. end, it has been proposed toconstruct the roll of layers of rubber and duck vulcanized or toconstruct the roll of rubber and horsehair. My ex"- perienoe, however,has been that the rolls so constructed have not proved satisfactory,

the first-mentioned roll not providing the necessary projecting pointsto accomplish the desired end, and the second-mentioned roll beingdefective in-that, the horsehairs break and. split and the points orprojections soon become worn ,ofi'. i i i i I have found that theprepared fiber from cocoanut husks, that is coir, may be used to greatadvantage in the manufacture of such rolls, and that, being tough anddurable, the points formed by the projecting ends of the fibers do notbreak ofl or wear away, in consequence of which a roll provided withsuch fibers may be used for a very considerable length of time withoutrenewal. The fibers may be incorporated in the roll in a variety of waysas I will explain in the following specification, but, in any event,they are so located that, when upon the roll, they are approximatelyradial to provide minute points which project slightly beyond the periphery of the rubber or duck in which they are embedded so as toproperly engage and draw the fibers over the stationary blade of themachine.

Referring to the drawings,Figure 1' represents a sectional view of acotton gin or wool burrer machine and shows some of the essential'partsthereof. Fig. 2 represents a plan view of the roll and what is termedthe feed. 7 Fig. 3 represents a roll constructed in accordance with myinvent-ion. Fig. 4 represents a longitudinal section through the same.Fig. 5 illustrates somewhatconventionally the manner in which thecovering of the roll is made. Fig. 6 illustrates a sectional view ofanother form of roll embodying the invention. Fig. 7 illustratessomewhat conventionally the manner of making the disks of which the rollcovering is formed. Figs. 8 and 9 represent other forms of disks inwhich the coir is incorporated.

Briefly a machine, in which the roll may be utilized, may be describedas follows. It includes: a stationary blade at with which cooperates anoscillating blade I). The latter is mounted on an oscillating member 0which carries the feed. Contiguous to the stationary blade is the rollindicated as a whole atd. The feed includes the bottom board 6 having acomb f at the end through which the seeds, from which the cotton hasbeen stripped, will drop,

coiled about it, with its convolutions contiguous, an elongated strip11, said strip being fastened in place by any convenient means and beingclamped at the ends of the roll between collars 12. Projecting from theends of the wooden arbor are shafts or trunnions 13. The strips 11 arecut from sheets of which one is conventionally illustrated in Fig. 5.Each sheet consists of a plurality of layers of rubber indicated at 14with intermediate layers 15 of a woven fabric made of cocoanut fiber. Ifdesired, the layers 14 may be made of duck faced with thin coatings ofrubber. In any event, the sheet made of the various layers is vul- Fig.2, the oscillating blade is not shown. The roll cl maybe made in ava-Triety of ways. As shown in Figs. 3 and 4:, it consists of a woodenarbor 10 having canized in any suitable apparatus and is then cut instrips and the strips wound about the arbor as indicated. It is quiteevident that, insteadof forming the cocoanut fiber into a fabric beforeincorporating it in the sheet, the fibers may be laid loosely betweenthe layers of rubber and rubber and duck. In Fig. 6, I have illustratedanother form of roll embodying the invention, in which 16 indicates asleeve or arbor formed of brass having threaded ends on The sleeve maybe mounted upon a shaft 18 which is shown as keyed at 19. In this formof construction, the covering for the roll consists of a plurality ofdisks which are all placed upon the arbor and vulcanized. While thereonso as to adherent to the brass. In Fig. 7, I have shown one of the disksas consisting of a plurality of superimposed layers of rubber and coirfabric, the rubber layers being indicated at 20 and the fiber layers at21. In Fig. 8, however, the fibers are shown as not woven into a fabricbut as laid radially of the disks. The manner of forming a disk of thischaracter would be to place upon a layer of rubber the fibers allarranged radiever, that the disks may be vulcanized bestands or ropes,

ally to form a layer, upon which I would then place a layer of rubberand another superimposed layer of fibers, until the disk is of properthickness. It is evident, howfore being placed upon the arbor, or theymaybe partially vulcanized and then placed upon the arbor and thevulcanization then completed. The fibers may be twisted into as shown inFig. 9 at 22. covering formed in any of I have described, is highly Aroll, having a the ways which eflicient when as herein described. Theends of the coir serve to of the cotton or wool, to

minute projecting cating blade to strip from such fibers the seeds orthe burs. As previously stated,l the coir being tough and durable, thepoints are not broken off even after very long usage.

Having thus explained the nature of my said invention and described away of constructing and using the same, although without attempting toset forth all of the forms in which it may be made or all of the modesof its use, what I claim is: which are screwed the clamping collars17 1.
